[astropy/astropy] --open-files did not catch ResourceWarning

[pllim]

If this is not really an issue, feel free to close, as I am not familiar with the internals of open files check. Example log: https://travis-ci.org/astropy/astropy/jobs/442639768

It seems weird to me that --open-files option still reported passing despite the presence of following warning:

sys:1: ResourceWarning: unclosed file <_io.BufferedWriter name=13>

Moved from astropy/astropy#7913

I'm inclined to say that this is not actually an issue in this plugin. See the discussion here: astropy/astropy#7913 (comment)

I'm reopening this issue and reinterpreting it as a feature request 😉. See #15 for related discussion.

This plugin should no longer be used, please see:
